| Abstract | This report details an approach to the real-time coordination of large networks of short-range sensors that communicate over short-range, low-bandwidth, high-latency radio channels. Each sensor is limited in the distance over which it can scan and in the type of data that it can acquire, so nearby sensors must collaborate to acquire complementary data for accomplishing such tasks as multipletarget detection and tracking. Operational limitations on sensors and real-time requirements on tasks restrict the number of tasks in which a given sensor can collaborate. The quality with which a given task is accomplished and the cost incurred are affected by which particular sensors collaborate in achieving the task. Consequently, a coordination mechanism is required to optimize collaboration. The coordination mechanism reported is fully distributed — each sensor decides for itself which measurements it should take to achieve optimal collaboration with nearby sensors, based what it knows about their intended measurements, and informs those sensors of its own intentions so that they can likewise optimize their own measurements. In order to determine which measurements are optimal, a sensor must have knowledge about the targets that are the intended subjects of the measurements. To this end, each sensor exchanges measurement data with nearby sensors, and operates a data fusion process to maintain local target estimates. The reported coordination mechanism is claimed to be scalable, low-cost, adaptive and robust. |
